An anatomical reduction and maintainance of articular fracture is on of the basic principles In Orthopedic Surgery if good function is to ensue, especially in a major welght bearing joint such as hip knee ankle. In displaced articular fractures, excellent results can be achieved mainly by an open anatomical reduction and firm internal fixation. We performed an open reduction and internal flxation with plates and screws in a patient with the severely comminuted acetabular fracture, and a satisfactory result is obtained.

BACKGROUND: The large volume of blood products are required during orthotopic liver transplantation. Any preoperative and intraoperative factors may influence the intraoperative blood products usage. METHODS: We retrospectively reviewed the demographic information, coagulation screens, thrombelastographic variables, and intraoperative blood requirements in 952 adult patients, who underwent orthotopic liver transplantation at the University of Pittsburgh Medical Center between January 1992 and December 1995. A preoperative coagulation abnormality score (CAS) was calculated by assigning one point of each abnormal result of the coagulation tests (PT, aPTT, platelet count) and thrombelastographic variables (reaction time, alpha angle, maximal amplitude, clot lysis index). Intraoperatively, blood products and pharmacologic coagulation therapy were administered based on thrombelastographic and hemodynamic data. RESULTS: Underlying liver disease, retransplantation one month after the first transplantation, poor preoperative coagulation profiles were predictive of intraoperative blood usage. Age, preoperative PT >15 sec, and CAS were not predictive of intraoperative blood usage. The severe fibrinolysis during operation occurred. More blood products were required in patients with severe fibrinolysis. CONCLUSIONS: The understanding of preoperative and intraoperative factors affecting blood product requirements can help the management of blood component therapy during liver transplantation.

Sarcoidosis is a disease of unknown cause characterized by the presence of noncaseating granulomatous inflammation. Because the lungs and thoracic lymph nodes are almost always involved, most patients report acute or insidious respiratory problems. Although pulmonary manifestations are usually the major clinical concern in sarcoidosis, extrapulmonary involvement is common. We report a case of sarcoidosis of the axillary lymph nodes with no evidence of lung alteration.

Extravaginal neonatal testicular torsion, although it is rare, is being recognized with increasing frequency. Furthermore, bilateral neonatal torsion is very uncommon. Because of the seriousness of the outcome due to the risk of future anorchia, this condition that requires prompt recognition and careful decision making. We experienced a case in which the patient had bilateral neonatal testicular torsion and the patient showed bilateral necrotized testes during operation. However, the histopathologic findings during operation showed a small intact portion only in the left testis. Right orchiectomy and left orchiopexy were performed, and the left testis was saved. We report here on this case with a review of the literature.

The isolation of fetal cells from maternal circulation has the potential to allow relativelyself prenatal diagosis for all pregnant women. The present technology, however, has notreached the accuracy required for clinical diagnosis because of maternal cell contaminationSo we published a new method for enrichment of nRBC in a fetal cell isolation(1996).In this study, attempted to FISH analysis of nRBC which was isolated by our ownmethods. We evaluated the efficiency of FISH.As the results, we have successfully used FISH on enriched nRBC.We were able to identified 2 abnormal fetus which were confirmed by conventionalcytogenentic study as Down syndrome(Fig.1) and Klinefeltre syndrome(Fig.2). And thesensitivity and specificity for FISH was 86%(49/57) and 92.3%(36/39), respectively.According to our results, fetal cell analysis by FISH can be reliable used for prenatalaneuploidy diagnosis. However, the problems of enrichment of the fetal cell and FISH probeor condition should be over come before analyze.

Sarcoma of the kidney is a rare condition. Leiomyosarcoma is the most common of the kidney sarcomas. Renal leiomyosarcoma usually originates from the smooth muscle layers of the kidney, for example, the renal capsule and renal vessels. Renal pelvis neoplasms, however, are primarily transitional cell carcinomas, and renal pelvis leiomyosarcomas are extremely uncommon. Renal pelvis leiomyosarcoma has never been reported in Korea. Moreover, no more than 10 cases have been reported internationally. However, none of these were associated with kidney abnormalities. Here we describe a case of leiomyosarcoma that originated from the blind end of a bifid renal pelvis.

PURPOSE: To evaluate the clinical usefulness of functional MR imaging (fMRI) for localization of the cerebral motor and sensory cortices and the language center in patients with complex partial seizure. MATERIALS AND METHODS: A total of 47 fMRIs were obtained in 14 patients (M:F=9:5; age 15 -50 years; 13 right handed and 1 ambidextrous) with complex partial seizure (6 temporal lobe epilepsy, 6 frontal lobe epilepsy, 1 occipitotemporal lobe epilepsy, 1 hemispheric epilepsy). Conventional MR imaging revealed no abnormality in four patients, localized cerebral atrophy in one, hippocampal sclerosis in four, and benign neoplasm in the remaining five. fMRI was performed on a 1.5 T MR scanner (GE Signa Horizon) using gradient-echo single-shot EPI. Nineteen fMRIs were obtained in eight patients who performed the language task, 16 fMRIs in ten who performed the motor task and 12 fMRIs in ten who performed the somatosensory task. The activation task consisted of three language tasks (silent picture naming, word generation from a character, categorical word generation), motor tasks (opposition of thumb and index finger for hand/dorsiflexion or extension for foot), and sensory tasks (passive tactile stimulation of hand or foot using a toothbrush). The data were analyzed using z-score (p<0.05), clustering, and cross-correlation analysis based upon homemade software, IDL 5.1. The success rate for obtaining meaningful fMRI was evaluated and activated regions were assessed on the basis of each fMRI obtained during language, motor, and omatosensory tasks. fMRI findings were compared with those of the Wada test (n = 7) for language lateralization and with invasive cortical mapping (n = 3) for the localization of eloquent cerebral cortex, especially around the central sulcus. RESULTS: The overall success rate of fMRI was 79 % (37/47); success rates of fMRI with language, sensory, and motor tasks were 89 % (17/19), 83 % (10/12), and 63% (10/16), respectively. Areas activated during language tasks (n=17) included the dorsolateral prefrontal cortex (16/17), anterior cingulate gyrus (16/17), posterior parietal area (15/17), Wernicke's area (10/17), and Broca's area (8/17). Regions activated by motor and somatosensory tasks (n=20) included the central sulcus (16/20), prefrontal cortex (15/20), posterior parietal cortex (9/20), supplementary motor area (6/20), and temporal cortex (3/20). The results of fMRI were concordant with the Wada test in six of seven subjects (86%) for language lateralization of left hemispheric dominance and with invasive cortical mapping in two of three patients (67%) for localization of the motor and sensory cortices. CONCLUSION: fMRI was successful in approximately three-quarters of patients with complex partial seizure, but at present appears to be an inadequate alternative to current invasive studies. Further clinical investigation is needed.

BACKGROUND: Thoracoscopic Sympathicotomy (TS) is widely accepted as an effective method for the treatment of palmar hyperhidrosis. Single lumen endotracheal tube using CO2 insufflation is a simple and safe method for thoracoscopic surgery. However, there are chances of CO2 embolism during CO2 insufflation and nerve dissection. The object of this study were to assess the incidence of embolic events using transesophageal echocardiography (TEE) and to evaluate the related cardiorespiratory consequence during TS. METHODS: Thirty-two patients undergoing TS were studied. The long axis four chamber view was obtained continuously, except for predetermined intervals (after induction, CO2 insufflation in left thoracic cavity, left sympathicotomy, CO2 insufflation in right thoracic cavity, and right sympathicotomy) where the transgastric short axis view was obtained to derive ejection fraction (EF). Heart rate, mean arterial pressure (MAP), O2 saturation, and end tidal CO2 were monitored. Statistical analysis was performed using multivariated ANOVA and unpaired Student's t-test. P < 0.05 was considered significant. RESULTS: We observed CO2 embolism in 28/32 patients during CO2 insufflation (left or right) and in 32/32 patients during nerve dissection (left or right). There was no significant difference in cardiorespiratory variables between patients who presented embolism and who did not, during four distinct periods of events. Meanwhile, MAP decrease (P = 0.002) and EF increased significantly (P = 0.007) after sympathicotomy. This can be explained by decrease in systemic vascular resistance (SVR) by sympathicotomy. CONCLUSIONS: Embolic events commonly occur during CO2 insufflation and nerve dissection without cardiorespiratory instability during TS. However, we should pay attention when administrating N2O.

PURPOSE: Diabetic nephropathy is the most serious of complications in diabetes mellitus. Thiazolidinedione (TZD) is thought to ameliorate diabetic nephropathy; however, the mechanism underlying this effect has not been elucidated. We hypothesized that the vascular endothelial growth factor (VEGF) participates in the pathogenesis of diabetic nephropathy and that TZD may be beneficial for the treatment of diabetic nephropathy because of the effect it has on VEGF. MATERIALS AND METHODS: 23 Otsuka- Long-Evans-Tokushima-Fatty (OLETF) rats and eight control Long-Evans-Tokushima-Otsuka (LETO) rats were divided into the following four groups: LETO group, control OLETF group, pioglitazone treated group (10mg/kg/day), and rosiglitazone treated group (3mg/kg/day). RESULTS: A progressive increase in urinary protein excretion was observed in the diabetic rats. Glomerular VEGF expression in the control OLETF rats was significantly higher than in the control LETO rats. However, there was a significant reduction in both the glomerular VEGF expression and the VEGF mRNA levels after treatment with pioglitazone and rosiglitazone. The twenty-four hour urine protein levels were significantly decreased in both groups of the treated OLETF rats. CONCLUSION: These results suggest that TZD may have beneficial effects on diabetic nephropathy by reducing the VEGF expression.

PURPOSE: To determine whether 1H magnetic resonance spectroscopy (MRS) is useful in differentiating idiopathic Parkinson's disease (IPD) from progressive supranuclear palsy (PSP), based on metabolite ratios. MATERIALS AND METHODS: Using a 1.5 T MR Unit, single voxel 1H MRS using STEAM with a TR of 2000ms and a TE of 135ms was performed in seven PD and eight PSP patients. Five age-matched volunteers(mean age, 63 years) andanother five younger healthy volunteers(mean age, 30 years) were studied as normal controls. The regions of interest were the putamen and pallidum, with a size of 2 X 2 X 2cm. After measuring the spectral intensities ofeach metabolite (N-acetylaspartate=NAA, choline=Cho, creatine=Cr and lactate), relative peak height ratios ofNAA/Cr, Cho/Cr and Naa/Cho, and lactate levels among four groups were compared. ESULTS: NAA/Cho and NAA/Crratios were statistically lower in the PSP group than the IPD group (1.21 +/-0.26 versus 1.45 +/-0.20, and 1.26 +/-.23 versus 1.38 +/-0.19, respectively : p<0.05). NAA/Cho and NAA/Cr ratios were significantly lower inage-matched controls than in younger normal controls (1.39 +/-0.21 versus 1.76 +/-0.15, and 1.36 +/-0.13 versus1.79 +/-0.17, respectively : p<0.05). However, NAA/Cho and NAA/Cr ratios between age-matched controls and IPD werenot significantly different (p>0.05). Cho/Cr ratios were not different among four groups. Lactate was not detectedin any patients. CONCLUSION: NAA/Cho and NAA/Cr ratios in the corpus striatum were significantly lower in the PSP group than in the age-matched control and IPD groups. These results suggest that loss of neuron cells in thecorpus striatum is more prominent in PSP than in IPD, and that NAA/Cho and NAA/Cr ratios may help in differential diagnosis of IPD and PSP.
